A Pentium 166MHz or faster processor with at least 32 megabytes of physical RAM is required to run graphically based applications. Forty-eight megabytes of RAM is recommended for applets running within a browser using the Java Plug-in product. Running with less memory may cause disk swapping which has a severe effect on performance. Very large programs may require more RAM for adequate performance.
You should have 70 megabytes of free disk space before attempting to install the Java 2 SDK software. If you also want to install the documentation download bundle, you will need an additional 120 megabytes of free disk space.

Then follow the instructions the installer provides. When done with the installation, you can delete the download file to recover disk space.3. Delete the downloaded file(s) (Optional)
If you want to recover disk space, delete the file (or files) you originally downloaded.4. Update the PATH variable
You can run the Java 2 SDK without setting the PATH variable, or you can optionally set it as a convenience.
The CLASSPATH variable is one way to tell applications written in the Java programming language (including the Java 2 SDK utilities) where to look for user classes (classes that you develop). (The
Your computer system should now be ready to use the Java 2 SDK. In this step, you'll run some simple commands to make sure it is working properly.
